Which funds own PI
Impinj Inc in the Q2 2026 filings. At least 2 of the 91 current managers on file reported a position, worth $80m between them. It is among the largest positions of fewer than a fifth of the current managers on file. Buying and selling roughly cancelled this quarter, which is what a name looks like when the argument is still live.

Only each manager’s largest 200 positions are listed here, so a smaller holder may be missing.
Managers reporting a position
Largest first. Weight is the share of that manager’s whole reported book, which is the number worth quoting: $400m is a rounding error in one book and a defining bet in another.
| Manager | Value | Weight | Shares | Change on the quarter | Action |
|---|---|---|---|---|---|
| Whale Rock Capital Management LLC Long/short equity · $12.5bn book | $58m | 0.5% | 405,244 | +$16m0 | Held |
| Baillie Gifford & Co Long-only · $110bn book | $22m | 0.0% | 155,965 | +$4.5m-18,150 | Trimmed |
Sold out of this quarter
Valued at what the position was worth in the previous filing, because by this one it is gone.

Ownership through time
At least 8 of the 95 managers whose filings are on file listed PI in Q2 2026, against 1 in Q4 2016. 4 managers more than in Q1 2026: 4 listed it again.
Each manager’s largest 500 positions a quarter are read, so a small holding in a very large book can be missing, and a manager is counted as leaving only where its own filing shows it.

What PI is worth
Knowing who owns it is half the question. The other half is what it is worth against the companies it trades beside, which is the one an interviewer will follow up with.
Build the comp set around PI →How much of the picture this is
A Form 13F reports US-listed long equity and nothing else: no shorts, no bonds, no cash and no non-US listings. It arrives forty-five days after the quarter ends, so a manager who sold in July still shows the position in a filing published in August. This page reads the managers on file here rather than every filer in the market, and each manager’s largest positions rather than the whole table, so a small position in a very large book may not appear. Say “their last filing showed” rather than “they own”, and the distinction will do you credit.
What to do with a name the funds are buying
Knowing who owns something is the start of a pitch, not the pitch. The next questions are what it is worth and why they were buying.
